This paper presents a methodology for the design of vibration abatement solutions to be applied in railway tunnels in the context of problems where an already operative underground railway infrastructure is inducing excessive vibration levels to particular nearby buildings. In such cases, where some parts of the global system are already constructed, the inclusion of experimental data measured at the specific site to be studied increases significantly the accuracy and reduces the uncertainty of the predictive model. This paper proposes to use experimentally measured vibration transmissibility functions between the tunnel wall and the particular buildings to be studied as a model of the tunnel/soil/building system. This model, combined with a numerical model of the tunnel/track system, forms the global hybrid approach presented in this paper. Vibration abatement solutions can be included in the tunnel/track model in order to assess their efficiency. This methodology can be used for the study of any vibration abatement solution to be applied in the tunnel structure. In this paper, two types of these solutions are specifically studied: rail fastening system retrofitting in order to modify the rail fastener stiffness and the application of dynamic vibration absorbers.
